背景：平衡功能障碍可能会使人虚弱，并可能导致灾难性的后果，如摔倒。内耳前庭系统是平衡控制的重要组成部分。然而，据我们所知，前庭功能障碍在美国的患病率以及与前庭功能障碍相关的跌倒风险增加的幅度从未被估计过。这项研究的目的是确定美国成年人前庭功能障碍的患病率，通过社会人口学特征评估差异，并估计前庭功能障碍与跌倒风险之间的关联。方法：我们收集了2001-2004年全国健康和营养检查调查的数据，该调查是对美国40岁及以上成年人(n=5086)的横断面调查。结果：从2001年到2004年，35.4%的40岁及以上的美国成年人(6900万美国人)有前庭功能障碍。前庭功能障碍的几率随着年龄的增长而显著增加，高中以上教育程度的人患前庭功能障碍的几率降低40.3%，糖尿病患者患前庭功能障碍的几率高70.0%。有临床症状(即头晕)的前庭功能障碍的参与者跌倒的几率增加12倍。结论：通过简单的姿势测量来衡量前庭功能障碍在美国成年人中很常见。前庭功能障碍显著增加了跌倒的可能性，跌倒是影响老年人的最病态和最昂贵的健康状况之一。这些数据表明了诊断、治疗和潜在筛查前庭缺陷的重要性，以减轻美国与跌倒相关的伤害和死亡的负担。阿奇实习生医院。2009；169(10)：938-944
Background: Balance dysfunction can be debilitating and can lead to catastrophic outcomes such as falls. The inner ear vestibular system is an important contributor to balance control. However, to our knowledge, the prevalence of vestibular dysfunction in the United States and the magnitude of the increased risk of falling associated with vestibular dysfunction have never been estimated. The objective of this study was to determine the prevalence of vestibular dysfunction among US adults, evaluate differences by sociodemographic characteristics, and estimate the association between vestibular dysfunction and risk of falls.Methods: We included data from the 2001-2004 National Health and Nutrition Examination Surveys, which were cross-sectional surveys of US adults aged 40 years and older (n = 5086). The main outcome measure was vestibular function as measured by the modified Romberg Test of Standing Balance on Firm and Compliant Support Surfaces.Results: From 2001 through 2004, 35.4% of US adults aged 40 years and older (69 million Americans) had vestibular dysfunction. Odds of vestibular dysfunction increased significantly with age, were 40.3% lower in individuals with more than a high school education, and were 70.0% higher among people with diabetes mellitus. Participants with vestibular dysfunction who were clinically symptomatic (ie, reported dizziness) had a 12-fold increase in the odds of falling.Conclusions: Vestibular dysfunction, as measured by a simple postural metric, is common among US adults. Vestibular dysfunction significantly increases the likelihood of falls, which are among the most morbid and costly health conditions affecting older individuals. These data suggest the importance of diagnosing, treating, and potentially screening for vestibular deficits to reduce the burden of fall-related injuries and deaths in the United States.
